Question

calculate the work done by lifting a 10 kg object 10 m from the surface of the earth​

Answer 1

Answer:

981 J

Explanation:

We know, work done=$\large\blue {m*g*h}$

Given, Mass=$\green {10k.g.}$

Height=$\green {10metres}$

We take "g" as$\green {10m/s²}$ [You can also assume it to be 10m/s² to make calculations simple.]

So, Work done =$[10*10*9.81]J$=$981 J$
